Description
The Actuator Pressure Controller (APC) is a pressure control system
developed for the calibration and testing of pneumatic control
boxes.
With this APC, it is possible to generate a pressure or vacuum level
to be reached instantly or with a predefined control ramp. In
addition, an external sensor can be used to measure the pressure
obtained.
It is possible to check the calibration of a pneumatic control box
with a complete hysteresis cycle, defining all the parameters of the
adjustment process. The pressure data from the sensors is recorded and
analysed to check the maximum permissible hysteresis, either as an
absolute value or as a proportion of the movement of the control
box.
Different control configurations can be saved and reloaded on
demand.
The calibration control cycles are carried out via 3 ports, 2 inlets
from the test bench supplying the APC box with dry and clean air under
pressure of up to 1 bar and a negative pressure of -800 mbars minimum,
and an outlet driving the pneumatic control box. This is the outlet
that will receive the external pressure sensor if necessary.
The control valve integrated into the APC is precisely regulated to
generate time-based pressure ramps or to reach a vacuum or pressure as
quickly as possible.
The APC is equipped with a National Instruments cRIO board with a
real-time operating system that ensures consistent response times and
deterministic results.
The APC is able to communicate with various interfaces such as PLCs
and PCs via Ethernet or RS232 links. Communication with PLCs is
implemented via a proprietary protocol, while RS232 communication is
based on GE-Druck's standard DPI520 protocol.
